Tokina 20-35 AF Mark I - Focusing ring "rattle"

Hi. So I've purchased this lens off ebay in excellent condition, arrived very quickly (from Japan). Seems to be in excellent shape, no scratches/fungus/haze/dents, even mount looks
barely used. One thing I've noticed is that the focus "rattles" a bit, like it's fairly loose. With AF disabled on camera, focus takes no effort at all, like there's no resistance to rotating the focus ring.
With AF enabled the focus ring doesn't rotate fully (with the screw driver holding it in place), but it's not a complete lock, it moves a tiny bit left/right.

Is this normal behavior of this particular model, or it can be fixed? I understand it's an older lens, and it doesn't bother me much, but after reading multiple "built like a tank" reviews, it's a bit surprising
to see) I think I have few days to return it in case it's not fixable I believe. Optically it seems pretty good, haven't taken it out to the field yet, just quick tests. Another thing I've noticed - it over exposes
in some scenarious, by about +1EV, sometimes more.

Thanks!
